BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

The present invention relates to novel bradykinin antagonist compositions comprising at least one extract of at least one plant of the Rosaceae family.

This invention also relates to the administration of at least one plant of the Rosaceae family, as the active species or agent for treating disorders associated with an excessive synthesis and/or release of bradykinin.

2. Description of the Prior Art

Bradykinin is a peptide of plasma origin which is released from a kininogenic precursor by a plasma protease deemed kallikrein (EC 3.4.21.24). This nanopeptide is one of the key mediators of inflammation and exhibits mitogenic properties. The receptors for this kinin can be separated into two principal subtypes B1 and B2. Bradykinin acts especially on the B2 receptor and causes stimulation of numerous systems of production of second messengers, including inositol triphosphates (ip3), known to cause the release of calcium from the intracellular storage sites in the cells including the keratinocyte. Bradykinin also induces the phosphorylation of tyrosine residues through activation of the B2 receptor, depolarization or hyperpolarization of the cell membrane, as well as the activation of the metabolism of arachidonic acid.

Bradykinin is involved in a large number of physiopathological disorders such as, for example, vasodilation and increase in vascular permeability, hypotension, pain or the proliferation of the connective tissue. Vasodilation and increase in vascular permeability may have as consequence, inter alia, acne rosacea, telangiectasia or a rhynophyma. The proliferation of the connective tissue results in the formation of keloids.

Bradykinin is suspected of playing a role in the mechanism leading to hair loss.

Moreover, bradykinin causes an inflammatory response by activation of phospholipase A2 and by formation of prostaglandins and/or the release of various inflammation mediators, cytokines, leukotrienes. It is also involved in the stimulation of nerve endings, the contraction of the smooth muscles of the digestive and respiratory tracts and of the uterus. An excessive production of bradykinin may cause diarrhoeas in gastrointestinal disorders and stimulate the nasopharyngeal secretions in allergic rhinitis.

Bradykinin is moreover known to stimulate ion transport and fluid secretions by various epithelia.

The administration of bradykininergic antagonists is therefore one of the effective alternatives to all cosmetic and/or pathological disorders involving the systems described above, in particular inflammatory processes of neurogenic origin or otherwise.

For a substance to be recognized as a bradykinin antagonist, it should induce a coherent pharmacological response including or otherwise its attachment to the bradykinin receptor.

Thus, within this definition is any compound which may interfere with the effects of bradykinin by its attachment to the receptor for the latter (B1 or B2) and/or any compound which, independently of the attachment to the receptor(s), induces by any mechanism an effect which is the opposite of that known for bradykinin (for example, interfering with the synthesis of bradykinin).

In particular, for a substance to be recognized as a bradykinin receptor antagonist, it should, in particular, exhibit the following characteristics:

(a) have a selective affinity for the receptors specific for this compound: of the B1 and/or B2 type. The experimental models used are established on a culture of mesenteric aorta cells (receptor attachment to B1 receptors according to the technique described by J. P. Galizzi published in Brit. J. Pharmacol, 113, 389 (1984)) and/or on the intestine (receptor attachment to B2 receptors according to the technique described by Burch R. M. published in Biotech. Update (Dupont-Nen), 7, 2 (1992); and/or

(b) have a bradykinin receptor antagonist pharmacological activity, namely, induce a coherent pharmacological response in specific tests. The pharmacological activity is in this event evaluated on isolated organs according to the techniques described by Rhaleb N. E. et al., in Brit. J. Pharmacol., 94, 445 (1990) as regards an antagonist activity of the B1 and/or B2 type.

Numerous compounds have already been recognized as bradykinin antagonists. Representative are the optionally modified synthetic or natural peptides such as D-Arg-[Hyp3, D-Phe7]-bradykinin (NPC567), [Thi 5, 8, D-Phe7]-bradykinin, D-Arg, [Hyp3, Thi5,8, D-Phe7]-bradykinin, N-α-adamantaneacetyl-D-Arg-[Hyp3, Thi5,8, D-Phe7]-bradykinin, des-Arg9, [Leu8]-bradykinin (all marketed by Sigma) or, alternatively, compounds described in WO-95/08566, WO-95/07294, EP-0623350, EP-0622361, WO-94/11021, EP-0596406, WO-94/06453, WO-94/09001, EP-0578521, EP-0564972, EP-0552106, WO-93/11789, U.S. Pat. No. 5,216,165, U.S. Pat. No. 5,212,182, WO-92/17201, EP-0496369, EP-0472220, EP-0455133, WO-91/09055, WO-91/02746, EP-0413277, EP-0370453, EP-0359310, WO-90/03980, WO-89/09231, WO-89/09230, WO-89/01780, EP-0334244, EP-0596406, WO-86/07263 or P-guanido-benzoyl-[Hyp3,Thi5,D-Tic7,Oic8]-bradykinin (S 16118) (Feletou M & al., Pharmacol. Exp. Ther., June 1995, 273, 1078-84), D-Arg-[Hyp3, Thi5, D-Tic7,Oic8]-bradykinin (HOE 140) (Feletou M & al., Eur. J. Pharmacol, 1995, 274, 57-64), D-Arg-[Hyp3, D-Hype (trans-propyl)7 Oic8]-bradykinin (NPC 17731) (Herzig M. C. S. and Leeb-Lundberg L. M. F., J. Biol. Chem., 1995, 270, 20591-20598) or those indicated in Bradykinin Antagonists: development and applications (Stewart J. M., Biopolymers, 1995, 37, 143-155), or, alternatively, synthetic or natural chemical molecules such as, for example, those described in Salvino et al., J. Med. Chem., 3, 2583-2584 (1993).

As a general rule, these bradykinin antagonists which, moreover, provide excellent results, are chemical molecules which may have harmful side effects.

Serious need continues to exist for novel active agents or species which meet the criteria for a bradykinin antagonist, especially if they are of natural origin and are devoid of side effects.

Heretofore, it has never been demonstrated or suggested in the prior art that an extract of at least one plant of the Rosaceae family exhibits the criteria for a bradykinin antagonist.

Indeed, plants of the Rosaceae family are principally used for their aromatic and ornamental properties.

In the prior art, plants of the Rosaceae family have been included in compositions for the treatment of urogenital diseases (FR-76/36295), in lightening cosmetic compositions (JP-08208451) or in compositions for protecting against ultraviolet radiation (EP-A-781544), for the preparation of antioxidant compounds (EP-A-94/401669), or, alternatively, for the preparation of antimicrobial and/or insecticidal compounds for the protection of plants (DE-4327792).

SUMMARY OF THE INVENTION

It has now unexpectedly and surprisingly been determined that extracts of at least one plant of the Rosaceae family elicit bradykinin-antagonizing activity.

Thus, it has now been determined that an extract of at least one plant of the Rosaceae family presents the characteristics defined as characterizing a bradykinin antagonist and can therefore be administered as a bradykinin antagonist.

Accordingly, the present invention features cosmetic/pharmaceutical compositions comprising an effective active agent amount of at least one Rosaceae extract which serves as a bradykinin antagonist.

DETAILED DESCRIPTION OF BEST MODE AND SPECIFIC/PREFERRED EMBODIMENTS OF THE INVENTION

More particularly according to the present invention, by “active ingredient” is intended any molecule or extract capable of modifying or of modulating the functioning of at least one given biological system.

The extract of at least one plant of the Rosaceae family may be any extract prepared from any plant material derived from at least one plant of the Rosaceae family.

Thus, the extract of at least one plant of the Rosaceae family according to the invention may be obtained from plant material derived from a whole plant, or from a plant portion such as the leaves, stems, flowers, petals, roots or from undifferentiated cells.

By “undifferentiated plant cell” is intended any plant cell exhibiting none of the characteristics of a specific specialization and capable of living or remaining viable by itself and not in dependence on other cells. These undifferentiated plant cells may be capable, under the influence of an induction, of any differentiation consistent with their genome.

According to the technique of culture selected, and in particular according to the selected culture medium, it is possible to obtain, from the same explant, undifferentiated plant cells having different characteristics.

Preferably according to the invention, petals are employed.

The extract of at least one plant of the Rosaceae family may be any extract prepared from any plant material derived from at least one plant of the Rosaceae family cultured in vivo or derived from in vitro culture.

By “in vivo culture” is intended any culture of a conventional type, namely, in the soil, outdoors or in a greenhouse, or, alternatively, soil-free culture.

By “in vitro culture” is intended the range of techniques known to this art which makes it possible to artificially obtain a plant or a portion of a plant. The selection pressure imposed by the physicochemical conditions during the growth of plant cells in vitro makes it possible to obtain a plant material which is standardized and available throughout the year, contrary to the plants cultured in vivo.

Preferably according to the invention, a plant derived from in vivo culture is employed.

Any extraction technique known to this art may be used to prepare the extract contained in the compositions according to the invention.

Exemplary are those utilizing, in particular, aqueous or alcoholic extracts, or extracts obtained from an organic solvent.

By “aqueous solvent” is intended any solvent consisting completely or partly of water. Exemplary are water itself, aqueous/alcoholic solvents in any proportion or, alternatively, solvents comprising water and a compound such as propylene glycol in any proportion.

Among the alcoholic solvents, ethanol is particularly representative.

An extract prepared by the method described in French patent application No. 95-02379, assigned to the assignee hereof, is also exemplary.

Thus, in a first step, the plant material is ground in an aqueous solution at cold temperature, in a second step, the particles in suspension are removed from the aqueous solution derived from the first step, and, in a third step, the aqueous solution derived from the second step is sterilized. This aqueous solution corresponds to the extract.

Moreover, the first step may advantageously be replaced by a simple operation of freezing the plant tissues (for example at −20° C.), followed by an aqueous extraction comprising the second and third steps described above.

Regardless of the mode of preparation according to the invention, subsequent steps intended to promote preservation and/or stabilization may be included without as a result modifying the actual nature of the extract. Thus, for example, the extract obtained may be freeze-dried by any conventional freeze-drying method. A powder is thus obtained which may be used directly or, alternatively, mixed in an appropriate solvent before use.

Preferably, according to the invention, an aqueous extract and even more preferably an extract prepared with a solvent composed of water and of propylene glycol marketed under the trademark Herbasol® by Cosmetochem, is used.

The Rosaceae family comprises 27 genera including, for example, the genera Agrimonia, Amygdalus, Armeniaca, Cerasus, Malus, Mespilus, Persica, Pirus, Prunus, Rosa, Rubus.

Thus, the Rosaceae extract of the invention is an extract prepared from material derived from at least one plant belonging to a genus selected from among Agrimonia, Amygdalus, Armeniaca, Cerasus, Malus, Mespilus, Persica, Pirus, Prunus, Rosa, Rubus.

Preferably, the plant belongs to the Rosa genus.

The Rosa genus comprises more than 1,000 species including, for example, Rosa alba, Rosa alpina, Rosa canina, Rosa cinnamonea, Rosa gallica, Rosa repens, Rosa rubrifolia, Rosa rubiginosa, Rosa sempervirens, Rosa spinosissima, Rosa stylosa, Rosa tomentosa or Rosa villosa.

Thus, the plant extract of the Rosa genus of the invention is an extract prepared from material derived from at least one plant belonging to a species selected from among Rosa alba, Rosa alpina, Rosa canina, Rosa cinnamonea, Rosa gallica, Rosa repens, Rosa rubrifolia, Rosa rubiginosa, Rosa sempervirens, Rosa spinosissima, Rosa stylosa, Rosa tomentosa, Rosa villosa.

Preferably, the plant belongs to the species Rosa gallica.

Exemplary disorders associated with an excessive synthesis and/or release of bradykinin were set forth in the above text.

The present invention thus features, as active ingredient, in a cosmetic/pharmaceutical composition, an effective amount of at least one extract of a plant of the Rosaceae family, the extract or the composition being well suited for treating physiopathological disorders associated with an excessive synthesis and/or release of bradykinin.

Thus, in one specific embodiment of the invention, an effective amount of at least one extract of a plant of the Rosaceae family is formulated into a cosmetic/pharmaceutical composition, the extract (i.e., the active agent/species) or the composition being well suited for treating vasodilation and increase in vascular permeability, hypotension, pain, proliferation of the connective tissue, inflammation, hair loss, diarrhoeas, allergic rhinitis, the contraction of the smooth muscles of the digestive and respiratory tracts and of the uterus.

The present invention more particularly features compositions comprising an effective amount of at least one extract of a plant of the Rosaceae family, the extract or the composition being useful for treating acne rosacea, telangiectasia, a rhynophyma or for preventing the formation of keloids.

Regardless of the form of the composition according to the invention, the amount of Rosaceae extract therein of course depends on the desired effect and can therefore vary widely.

In said examples to follow, all parts and percentages are given by weight, unless indicated otherwise.

EXAMPLE 1 Bioloaical Activity of a Rosa Gallica Extract:

The extract used in the tests presented here was a Rosa gallica extract marketed under the trademark Herbasol® by Cosmetochem.

(1) Measurement of the receptor affinity:

The measurement of the receptor affinity of the extract for the bradykinin B2 receptor was carried out according to the technique described by Jong, Y. J. L. et al., PNAS-USA, 90, 10994 (1993).

During each study, the reference molecule for the receptor studied (NPC567) was tested at eight (8) concentrations (n=2) in order to obtain a standard curve permitting the experiment to be validated.

There were thus obtained:

30% attachment for the extract at 1%

74% attachment for the extract at 5%

84% attachment for the extract at 10%.

The results of this experiment demonstrated affinity of the Rosa gallica extract for the human bradykinin B2 receptor at concentrations of less than 1%.

The IC50 value was close to 1%.

(2) Measurement of the bradykinin-antagonizing activity:

A functional test ex vivo carried out on the type B2 bradykinin receptors present on the jugular vein isolated from rabbits was carried out in order to demonstrate the type B2 bradykinin-antagonizing character.

The ex vivo experiments were carried out according to the Rhaleb, N. E. et al. technique described in Brit. J. Pharmacol., 99, 445 (1990).

After establishment in experimental tanks, the tissues (smooth muscles) were subjected to an initial tension of 1 g. An equilibration period of at least 60 minutes, during which the physiological solution was replaced several times and the initial tension readjusted, was then observed before adding the extract.

The experiments were performed in the continuous presence of atropine (3×10−6 M) of pyrilamine (3×10−6 M) and of indomethacin (10−6 M) in order to eliminate the indirect effects of mediators used during the stimulation of other types of receptor present on this tissue.

Each preparation was initially stimulated by a B2 agonist at the concentration of 3×10−9 M which induced contractions. A B2 specific antagonist then simply had to be placed in the medium to observe the disappearance of these contractions in a dose-dependent manner.

There were thus obtained:

48% attachment for the extract of Example 1 at 0.5%

79% attachment for the extract of Example 1 at 1%

97% attachment for the extract of Example 1 at 5%

These results evidenced that the Rosaceae extract had a bradykinin-antagonizing activity. This activity was preferably expressed on the B2 receptor.
